Metal bodies located in a steel-frame structure that are inherently bonded through construction require additional bonding.

In this context, the statement suggests that metal bodies already bonded through construction in a steel-frame structure require extra bonding. The correct understanding is that if these metal components are properly bonded during the construction process as part of the steel framework, they inherently possess adequate electrical connections to maintain safety against electrical surges and lightning strikes.

Additionally, the bonding within the steel frame, when performed according to standards, provides a continuous path for electrical currents, reducing the risk of injury or damage from lightning strikes. Therefore, no additional bonding is necessary if the original connections are sound and compliant with relevant codes and practices.

Thus, the assertion that additional bonding is required is false, leading to the conclusion that the originally proposed statement is incorrect.
